Question

In a clinical trial, 24 out of 893 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.4% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.4% of this drug's users experience flulike symptoms as a side effect at the a=0.1 level of significance? V 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. Because np. (1-P) = U 1 0, the sample size is (Round to one decimal place as needed.)

Answer 1

Here we have to test that

Ho: p=0.024

H1 :p > 0.024

po = 0.024

n = 893

n* po* (1 - Po) = 893 * 0.024 * (1 – 0.024) = 20.9 > 10

Because n*p0*(1-p0) = 20.9 > 10, the sample size is less than 5% of population size, the sample meets the requirements for testing the hypothesis satisfied.

H1 :p > 0.024
